How this lesson connects

Keep using what you learned last class: A message drives action because it is written at the audience's reading level and ends in a specific step, so the person both understands it and knows exactly what to do. Today: A public health product must aggregate identifying details because a name-free record can still be traced to one person through rare combinations, so protecting the individual requires coarsening the data, not just deleting names.

💡 Big idea: A product must aggregate identifying details because a name-free record can still be traced to one person through rare combinations, so protecting the individual requires coarsening the data, not just deleting names.

  1. 0-5 minWarm-up: name one type of health data you would NOT want shared without your permission
  2. 5-20 minList all personal or health data your product touches
  3. 20-40 minIdentify which items are individually identifiable; mark them for removal or aggregation
  4. 40-55 minDefine who should and should not have access; document access rules
  5. 55-70 minWrite a short privacy statement (3-5 sentences) for your product
  6. 70-80 minExit ticket: name one change to your product that reduces privacy risk
Mr. Mendoza's 5-minute intro
  • A product that leaks personal data undermines the trust it needs to be effective.
  • Today you'll audit your own product design for any data that could identify a specific person.
  • Even well-intentioned health apps have caused harm by collecting more than needed.
  • Writing a privacy statement is not optional: it's a professional design standard.
Know by the end
  • Individually identifiable health data requires consent and protection under HIPAA principles.
  • Aggregation and de-identification are standard strategies for reducing privacy risk.
  • A privacy statement communicates data practices to users and is a product design requirement.

PLTW connection and today's work

Open Problem 5 in your myPLTW course shell and navigate to the current activity, then audit your public health product for privacy and data-protection concerns.

Today's stopping point: The message draft is done; privacy review belongs in the product-design phase, so confirm your activity guide.

PLTW activity titles identify the course connection. If your account will not open, use the posted materials for today and tell Mr. Mendoza. Do not mark an online activity complete unless you completed it.

Need help? Choose a starting point

Need a running start
Start by listing only the data your product actually shows a user on screen. You cannot protect data you have not first written down, so this list is the whole job's foundation.
On track
Go through your data list, decide which items to remove or aggregate so no single person can be identified, and write a short privacy statement that says plainly what you collect and who can see it.
Stuck? Get unstuck
If you are stuck, apply one test to each data item: 'Could someone use this, plus one other field, to guess a specific person?' If yes, aggregate it (use a range or a bigger area) or cut it.
Push me further
Design a case where your product is technically name-free but still re-identifies someone, then fix it, and explain what threshold (like a minimum group size) prevents it.
Lesson resources: reading, slides, and vocabulary
Socratic teaching slide deck

The deck carries the prior idea forward, lets you inspect an analogy, maps the rule to biology, and ends with the same evidence decision and exit ticket used on this page.

Generated from this lesson's canonical data with a red-team citation check.

Carry forward

A message drives action because it is written at the audience's reading level and ends in a specific step, so the person both understands it and knows exactly what to do.

Daily take-home

A product must aggregate identifying details because a name-free record can still be traced to one person through rare combinations, so protecting the individual requires coarsening the data, not just deleting names.

Inspect the analogy

A review board sorts scientific evidence, stakeholder needs, possible benefits, possible burdens, and uncertainty before choosing a policy.

  1. Which statements are scientific evidence?
  2. Which statements express a value or priority?
  3. Who receives the benefit and who carries the burden?
Rule

Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.

Where it breaks

A review-board model organizes reasoning but does not make one ethical principle automatically outweigh every other principle.

Map the analogy to biology
  • Evidence cards map to source-backed findings.
  • Stakeholder cards map to affected people and priorities.
  • The recommendation maps to an explicit tradeoff with a named uncertainty.
Read this first

Driving question: Your product maps who in the neighborhood tested positive for something. How do you keep the map useful without turning it into a list that could out a specific person?

What you already know: A message drives action because it is written at the audience's reading level and ends in a specific step, so the person both understands it and knows exactly what to do.

New idea: A product must aggregate identifying details because a name-free record can still be traced to one person through rare combinations, so protecting the individual requires coarsening the data, not just deleting names.

Visual or model: F1. F1. A lesson illustration or teaching diagram for Privacy check. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Trace the labeled system, test, or design relationship and identify which evidence should trigger revision.

  1. Observe or measure the relevant feature in privacy check.
  2. Organize the observation with a stable evidence ID.
  3. Apply this rule: Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
  4. Choose the option the evidence supports and state the limit of the conclusion.

Real biomedical example: Your product maps who in the neighborhood tested positive for something. How do you keep the map useful without turning it into a list that could out a specific person?

What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.

What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.

Vocabulary:
  • audience: The specific group of people a product, message, or design is created for, whose needs and abilities shape every design choice.
  • privacy: A person's right to control who can access their personal or health information and how that information is shared.
  • usability: Use the lesson context and glossary entry to explain usability in your own words.
  • recommendation: A clear, evidence-based suggestion for what action to take, drawn from analyzing data, results, or a patient's situation.
  • evidence: The facts, data, and cases that carry your claim. Opinions are free; evidence costs homework.

Use it now: Choose one decision option. Cite E1 and E3, then explain how the rule connects the evidence to your choice.

Go further, optional: The source links below are optional enrichment. Every fact required for today's local evidence decision appears in this lesson package.

Evidence set and decision
E1 · Source fact

A defensible biomedical decision separates scientific evidence from value judgments, identifies who may benefit or be burdened, and states the uncertainty and tradeoffs that remain.

Limit: Scientific evidence can inform the options and likely consequences, but it cannot choose a single value-neutral answer.

E2 · Teaching model

Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.

Limit: A review-board model organizes reasoning but does not make one ethical principle automatically outweigh every other principle.

E3 · Task criterion

You identified identifiable data and reduced it.

Limit: E3 defines the classroom product or success criterion. It is not independent scientific evidence and cannot justify a clinical or causal claim.

PLTW-BFH-2027-04-27 · Simulated classroom evidence scenario

Your role: biomedical design team member

Decision: Your team must decide what the evidence from privacy check supports before submitting the notebook record named on today's page.

  • Combine small map areas into bigger ones so no age, zip, and condition mix points to one person.
  • Delete every name from the map data and share it, since data without names is already anonymous.
  • Nobody has looked at what other information about these neighbors could be matched against this map, so start there.

Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the notebook record.

Claim ceiling: Today's evidence supports a classroom claim about privacy check. It cannot prove causation, diagnose a real patient, or justify action outside this room.

Composite case file · PLTW-BFH-2027-04-27

Reason for review: Your team must decide what the evidence from privacy check supports before submitting the notebook record named on today's page.

Context: A product can protect the whole community and still betray individuals if it exposes data that can be traced back to one person.

Timeline:
  • T1: List any personal or health data your product collects or displays.
  • T2: Identify which items could identify an individual.
  • T3: Decide what data can be removed or aggregated.
  • T4: Note who should and should not have access.
  • T5: Write a short privacy statement for your product.
Evidence records:
  • E1: A defensible biomedical decision separates scientific evidence from value judgments, identifies who may benefit or be burdened, and states the uncertainty and tradeoffs that remain.
  • E2: Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
  • E3: You identified identifiable data and reduced it.

Measurements: Use only the measurements, units, graph, or counts supplied in today's task. No additional patient measurement is implied.

Figure finding: Teaching diagram for Privacy check. Trace the labeled system, test, or design relationship and identify which evidence should trigger revision. This is a teaching model, not patient or experimental data.

Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.

Math moment
Formula or setup

Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.

Worked parallel example

For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.

Units and reasonableness

Mean, median, and range keep the measurement unit. Order the values before finding the median.

Try it with today's data

Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.

Design record
Criteria
  • The solution must address the stated need in privacy check.
  • The decision must be supported by E1-E3.
  • The final product must make the success criteria visible.
Constraints
  • Complete the work inside the 80-minute block.
  • Use only supplied or teacher-approved materials and evidence.
  • Do not trade , accessibility, or privacy for speed.
Tradeoff weights
  • and evidence quality: must pass before scoring other criteria.
  • User need and effectiveness: highest scored criterion.
  • Time, cost, and ease of use: compare only after and effectiveness pass.

Test evidence: For each option, record the E1-E3 result that supports or fails each criterion. Do not assign a score without a named observation.

Watch the trap

Students often think Students believe that if they remove names, the data is automatically anonymous and safe to share.. The trap: Dropping names is not enough: a zip code plus an age plus a rare condition can re-identify someone just as surely as a name. Real de-identification means aggregating or coarsening data until no combination of fields points to one person, which is why counts in tiny areas are dangerous.

Worked example · a parallel case (guides, does not reveal)
Privacy audit and statement
Completes: Completes the privacy-review step of the public health product: a list of collected data, identifiable items flagged for de-identification, access rules, and a short privacy statement.

Data my product collects or displays:

  • Visitor name and phone number (sign-up form)
  • Child's age
  • Home ZIP code
  • Date of clinic visit

Identifiable items flagged: Name and phone number can identify a specific person, so they are the highest risk. ZIP plus exact date could also single someone out in a small area.

Reduce the risk:

  • Remove names from any public summary; replace with a count ('42 children vaccinated this week').
  • Report ZIP only at the neighborhood level, not paired with a single visit date.
  • Keep phone numbers only for reminder texts, never displayed.

Access rules: Only the clinic nurse and the program coordinator should see names and phone numbers. The public dashboard shows only aggregated counts.

Privacy statement (4 sentences): We collect your name and phone number only to send you a vaccine reminder. We never display your personal information publicly. Public numbers are totals only, with no way to identify any individual. You may ask us to delete your information at any time.

Why this matters
